Do the player has double jump after picking a powerup

I'm trying to start the double-jump only after he touch the object. Sorry for my english.

You need to give us a little more context.

Sounds like you want to use a Function that has whatever actions cause your character to jump.... twice?

Start with the double jump disabled in properties

When your player catches your powerup, adds event: player Platform behavior double jump set to enabled

try this event : your character on collision with the power up → action : your character , set double jump enabled

platfrom behavior should added to your character before you doing this event

Thank you for the precision androidpro

Platform behavior is actually necessary to realize what I had write
